DNS now working in VirtualBox client after network switch

I have a laptop and regularly change network connections. I don't shut the machine down but let it hibernate in between. I use VirtualBox, windows host (sorry, this is it for now but I promise it will change soon ;o), Linux guest.

I had to configure the Google free DNS service in the Linux guest so that the DNS works even when I change network (going home from work, etc.) :
